WASHINGTON, D.C. — Tomorrow, November 26, 2013, Robert Levinson will become one of the longest held Americans in history, passing the 2,454 days Terry Anderson spent in captivity before being freed in 1991.

Mr. Levinson, 65, is a retired U.S. government employee with 28 years of service to the Federal Bureau of Investigation and the Drug Enforcement Administration.On March 8, 2007, Mr. Levinson traveled to Kish Island, Iran, as a private investigator; he went missing the following day.

The FBI is responsible for investigating crimes committed against U.S. citizens abroad and has been conducting an investigation to locate Mr. Levinson since 2007. In March 2011, the United States government announced it had received indications that Mr. Levinson was being held somewhere in southwest Asia.

“Exhaustive efforts have not yet been successful in locating Bob or establishing a dialogue with those who are holding him, but the FBI remains wholly committed to bringing him home safely to his loved ones,” said FBI Director James B. Comey.“We will continue to follow every lead into his disappearance, and we ask anyone with information regarding his disappearance to contact the FBI.”

On the fifth anniversary of his disappearance in March 2012, the FBI announced a reward of up to $1 million for information leading directly to the safe location and return of Mr. Levinson; that reward still remains unclaimed.
